The seismic response of a bridge abutment is difficult to estimate due to complex soil-structure interaction. It becomes even more complex when the abutment is located on a slope. Although the earth pressure acting on a retaining wall and an abutment are of similar nature, the dynamic response of abutment can be significantly different due to participation of mass of the superstructure. In the present study, seismic response of a bridge abutment, located on slopes, was evaluated using 2D plane strain formulation, incorporating superstructure inertia. Design issues, such as distribution of earth pressure, design forces of the abutment stem, contribution of self-inertia, out-of-phase nature of earth pressure, and inertia force, were also discussed in detail. The design forces acting on the abutment were compared with the counterpart retaining wall. The earth pressure coefficients, obtained using finite element analysis, were compared with the Mononobe-Okabe method. The displacement of the abutment, obtained using finite element analysis, was compared with the value obtained using Newmark sliding block method. The seismic response of the abutment located on slope was compared with its counterpart on flat ground. Fragility curves were also developed to highlight the effect of slope on seismic response of bridge abutment.
